Cannot convert example from YAML to UCL using ucl_tool about libucl HOT 3 CLOSED

I'm not sure why you expect this to work?

The documentation that you linked to says "UCL is fully compatible with JSON format and is able to parse json files." Nowhere does it claim that it is capable of parsing generic YAML files.

Because both UCL and YAML are supersets of JSON some YAML documents are parseable by libucl (provided they don't use YAML-specific features like the --- document separator), but there are a huge number of YAML-specific features used in idiomatic YAML that are not compatible with UCL.

If it supports YAML output, I would assume it would support YAML input.

Perhaps it would be good to amend the documentation to reflect this.

If it supports YAML output, I would assume it would support YAML input.

That's a very questionable assumption, since that's not stated as a supported input format. It's also very clear just from looking at the unlinted output that it's not designed as a general-purpose YAML library and is just emitting YAML-flavoured UCL rather than idiomatic YAML.

Perhaps it would be good to amend the documentation to reflect this.

The README states multiple times that libucl is designed to parse UCL (and, by extension, JSON), the libucl API documentation states that it's a UCL parser, and the ucl_tool documentation clearly states that --format only applies to the output format.
